80393210 divided by 317 
We want to divide 80393210 by 317.

Going ahead to step 1:
The number 317 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 317

On to step 2:
317 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 317

On to step 3:
If we divide 803 by 317, we get 2 and a remainder of 169.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 634 away from 803, we end up with 169.
Take the next digit (9) from the dividend and append it to 169, then repeat: 1699 / 317

Let's proceed to step 4:
The number 317 fits into 1699 5 times, leaving a remainder of 114.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 114 after subtracting 1585 from 1699.
Include the next digit (3) from the dividend after 114, then repeat: 1143 / 317

On to step 5:
When dividing 1143 by 317, we get 3 with a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 253.0
Subtracting 951 from 1143 leaves us with 192.
Take the next digit (2) from the dividend and append it to 192, then repeat: 1922 / 317

Step 6:
317 goes into 1922 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 2536.0
Subtract 1902 from 1922 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 317

On to step 7:
317 can be fit into 201 0 times, resulting in a remainder of 201.
Record the quotient 0 as the next digit in the result. 
Result so far: 25360.0
Deduct 0 from 201 and we're left with 201.
Fetch the next digit (0) from the dividend, attach it to 201 and continue: 2010 / 317

Advancing to step 8:
2010 divided by 317 is 6 with a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 253606.0
The remainder is 108 after subtracting 1902 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 9:
317 goes into 1080 3 times with a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 253606.3
If we take 951 away from 1080, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 10:
When dividing 1290 by 317, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 253606.34
If we subtract 1268 from 1290, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
317 can be fit into 220 0 times, resulting in a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 253606.34
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
2200 divided by 317 is 6 with a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 253606.3406
Deduct 1902 from 2200 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 13:
The number 317 fits into 2980 9 times, leaving a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 253606.34069
If we subtract 2853 from 2980, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 14:
The number 317 fits into 1270 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 253606.340694
The remainder is 2 after subtracting 1268 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
If we divide 20 by 317, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 253606.340694
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
317 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 253606.340694
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 253606.340694 and a remainder of 2e-07.
